Summary: Simple companion to my Kinesis Advantage keyboard. I was unwilling to pay the money for the numeric pad offered by Kinesis (mostly because I do not use the number keys all day so extra ergonomic comfort here isn't a requirement). So I wanted something small and cheap that would sit next to my keyboard for times when I do need to enter numbers in. This is a small numeric pad, not full size in thickness or the keys (at least as far as I can tell).
Summary: I loved the price when I found this keypad. But The entire left side of the keypad didn't work. I had to press very hard to get the keys numlock, 7, 4, 1, and 0 to work; even then it wasn't consistent. I opened it up to see if something was loose, but nope. It's just defective.
Summary: I bought this keypad to use with a 3D modeling program called Blender, and it works great. It fits in my laptop case fine and seems like a solid little piece of equipment. The only complaint I have is the wire seems a little thin, but it hasn't been a problem so far.
